Tŷ Mawr Standing Stone
Solitary, strangely shaped Bronze Age monument
Probably erected at some point during the Bronze Age, this tall stone cuts a solitary figure standing alone amid fields on the outskirts of Holyhead. Measuring about 9ft/2.7m in height, the stone is notable for its unusual shape, seeming to twist around as it rises upwards from the ground.

Health & Safety
Care and attention must be paid when visiting this monument. It will be regularly exposed to the natural elements and may be slippery or muddy underfoot.
Appropriate footwear for the season and type of monument must be considered prior to your visit. Please only attend during the set opening hours, these have been chosen for your safety i.e. appropriate level of lighting.
Many of our monuments are located at areas of height, attention must also be paid therefore to the surrounding areas, ditches and moats when visiting.
Guardrails have been installed to prevent access to any areas of the site that we have deemed as dangerous or to prevent falls in specific areas. Please do not climb over or through any fixed installation.
Any handrail provided should be used to help you safely navigate historic steps, as these may be uneven and may be of different height.
As with all ancient monuments there is always a risk of stones being dislodged in bad weather, however, we manage this through extensive monitoring.
Climbing may result in serious injury.
There are several wild plants and flowers, although these are great pollinators, they may be poisonous to visitors and animals, we strongly advise you not to touch or allow dogs to eat any vegetation.
There may be shared access or neighbouring farmland that may involve the presence of grazing cattle or farm animals.
